fixitrod Posted October 13, 2004 Report Share Posted October 13, 2004 loco, if that is the case then you are correct. I'm anxious to see the final outcome. Quote Link to comment Share on other sites More sharing options...

fixitrod Posted October 13, 2004 Report Share Posted October 13, 2004 at first didnt it have a slight mid hesitation? now its got no bottom either? after passion ported it didnt you have someone else play with the exhaust port, if so thats where the bottom end went? but of course all this can only point to jims engine sucks, if it was me id send jim my whole motor and have him get it running right, before i busted his nuts in an open forum......

banshee04le Posted October 13, 2004 Report Share Posted October 13, 2004 Loco and Duece, I'm interested to know what size domes you guys are running? Are they the same size or not, and what compression reading do you guys get on a guage? My friend and I had the same drag port on our cylinders and ran the same carbs/intake and pipes. He had 17cc domes, but I couldn't run that much compression with nitrous. The difference was night and day on low and mid. I had a flat spot that I could not get jetted out, but his would lug a lower gear. Quote Link to comment Share on other sites More sharing options...

I added compression and damn what a difference. I was at 160psi and went to 192psi. Then added a lightened flywheel. It was night and day also. Funny thing is, Jim at Passion Racing is the one that helped me with what to do to get my motor to pull hard on the bottom.

reded Posted October 13, 2004 Report Share Posted October 13, 2004 My brother still hasn't got his running right yet. Has a dead spot in the middle and no amount of jetting will solve it. Oh yeah, he's the 2001 Minnesota state hillclimb champion in the 500cc class. Not to mention I was right on his ass the whole way and we've been racing together for 20 yrs. I think we both know a little something about jetting. Anyone wants to step up and figure that bitch out, be my guest. I've seen loco ride and he aint no slouch, If he says it won't run, it won't run. Quote Link to comment Share on other sites More sharing options...

theeechozen1 Posted October 13, 2004 Report Share Posted October 13, 2004 Im glad I read this post, I am getting ready to send my motor off for a 4mm build, I was really set on having passion do the work with all the raves of his 12 port. But I am looking into different options now. The last thing I want is not being happy with the power curve after dropping 2grand into my motor. Anybody have anything to say about Patriots 4mm Duner motor?? Thats what I am leaning towards now. Quote Link to comment Share on other sites More sharing options...

limitied03 Posted October 13, 2004 Report Share Posted October 13, 2004 I dont know much about the passion motor but i'll support loco....i read that post about jetting the passion stroker and there were alot of ppl that had the same exact problem and no where did anyone blame jim or bust his balls...... jus tryin to help, Quote Link to comment Share on other sites More sharing options...
Proquad101 Posted October 13, 2004 Report Share Posted October 13, 2004 Well guys all I have to say is my passion motor is the best running motor I have ever had. I dont want to say that you couple of guys that are having problems with your bikes dont know what you are doing when it comes to jetting, but if you have your jetting where it needs to be then I would probly look somewhere else for a problem like maybe the electrical system, are you guys still running all your stock ignition and coil or your plug caps. Like I said my bike runs like a bat out of hell but I have changed alot of things like my ignition and coil, plug caps. Quote Link to comment Share on other sites More sharing options...
tats4life Posted October 13, 2004 Report Share Posted October 13, 2004 ..i'm just running a long rod crank to give it more top end. I've got 195psi in each cylinder and i've raced jim's mx port and 12 port stroker........the stroker gave me a run but i still beat the guy by 2 bikes down the straight. i think the guy cant ride or isnt setup right, i race a patriot stroker every weekend and smoke him from top to bottom, street or dirt...i say just the oppisite of locco im on my tenth banshee and jims motor is the fastest ive ridden, smokes my trinity shee hands down....my friends with port magic bikes cant touch me either......loccos bike runs like shit and it aint jims fault mine runs tits...... the motors were running perfect and both guys could ride............just not as good as me, and didn't have enough ass to pass my ass......... .........i'm happy with my motor and your happy with yours............not tryin to start shit, or talk shit about other builders.

bansheefreak Posted October 13, 2004 Report Share Posted October 13, 2004 well i'm chime in here... i rode got1banshee--- banshee at the dunes and i was greatly disappointed.. i thought mine ran better then his and mine has just a few mods..i had half the money in my whole bike then he had in motor work... i gues he never got his running right cus he sold it... we never got to drag race but i wish we could have to see how my somewhat stock bike would do with his passion motor...now i know rick did not know alot about quads so i was not sure if it was just not tuned right or whatever but i have seen alot of post of ppl with same problems.... loco did you ride ricks banshee???it had awesome top end but thats bout all it had........
